1 Claim. 1

This invention relates to improvements in support for violon-cellos, andmore particularly to a novel support for violon-cello including a heightadjustment means.

An object of the invention is to provide a device of the type which,when adjusted, can be fixed at a selected height without danger ofslipping of the support.

Another object of the invention is to provide a device of the type whichwill not loosen by reason of vibration of the instrument to which it isattached during playing or use thereof.

Other and further objects of the invention will appear as thedescription proceeds, reference being had to the accompanying drawing,in which:

Fig. 1 is a view in elevation of the device detached from aviolon-cello.

Fig. 2 is a vertical sectional view of the device shown in place in thetail-pin of a conventional violon-cello.

In the drawing, the lower end wall H] of a violon-cello II, has gluedinteriorly thereof the block (2 which is apertured at l3 thereof toregister with an aperture I4 in the wall H]. A tail-pin I5 has a reducedupper end l6 which is held snugly within the apertures aforementioned.The tail-pin has a tapered bore longitudinally thereof, having itssmallest diameter at the upper end thereof.

The support member I! has a longitudinal bore at 58 for the entirelength thereof, and is exteriorly tapered at its upper end 19 to engagefor lodge within the complementary bore of the tail-pin IS. The supportmember H, at the lower end 20 thereof, has an exterior ferrule 2|encasing the same.

Within the lower end 20 and protruding downwardly from the same, is afixed interiorly threaded sleeve 22. An adjustable threaded extension 23is engaged with the interior threads of the sleeve 22. A lock nut 24 isthreadedly engaged with the extension 23.

In operation, the support I! is placed within the tail-pin IS. The locknut 24 is loosened sufficiently so that the member or extension 23 maybe turned within the sleeve 22 to the desired height. Then the desiredheight is ascertained,

the lock nut 24 is turned upwardly to bear tightly 5 against thedownwardly projecting portion of the sleeve 22. It will be seen that theextension 23 with its pointed foot 25 will thus be fixed withconsiderable security against accidental movement thereof.

It will be understood that the device is capable of many modificationsin construction and design, without departing from the spirit of theinvention, within the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, is:

In combination with the tail-pin of a Violoncello, an elongated tubularsupport member, an internally threaded sleeve fixed within the lower endthereof, a threaded extension rod engaged in said internal thread andadapted for movement in and out of said sleeve clear of the body of theviolon-cello, a floor-bearing point on the lower end of said extension,a cylindrical knurled por- 25 tion integral with said point, and aknurled setnut threadingly engaged on said rod adapted to be tightenedagainst the lower end of said sleeve to fix said rod in adjustedposition.
